WINDOW-SHUTTER OPERATOR AND FASTENER.

Specification of Letters Patent.

PatentedNov. 3, 1914.:

Application filed May 11, 1914. Serial No. 837,874.

To all whom it may cancer Be it known that I, J OHANNES JACOBSEN, subject of the Emperor of Germany, residing at Voorde, near Kiel, Germany, have invented certain new and useful Improve ments in Window-Shutter Operators and Fasteners, of which the following is a speci fication, reference being had therein to the accompanying drawing.

This invention relates to window shutters; and is designed to operate as a window shutter fastener. It is low priced, yet very effective device for its purpose, and is easily operated either from \iithin the room or from the outside of the Window.

The accompanying drawing illustrates the invention, in which Figure 1, is a longitudinal view of the de vice, partly in section. Fig. 2 is a plan view of Fig. 1, with the sash removed. Fig. 3 is a view similar to that shown in Fig. 2, but with the parts in different positions. Fig. 4k, is a perspective View of the double crank employed.

The various figures of the drawing are referred to by letters, similar letters denoting corresponding parts in the different views.

In prior devices there exists a dead center, whereby, in case of gustsof wind there arises a to and fro motion that causes unpleasant noises. These objections are all removed by the use of the invention which I will now describe.

In the drawing the reference character a, denotes a weather proof: casing in which are located the bearings for two double cranks b, 0, cl, and b, 0', d. The driving crank b, 0, cl, is actuated by a lever arm 6, in the room. The rods f and g, connect these double cranks with each other. The bearing trunnion carries a flat iron 2', to which the shutter k is fastened, so that the shutter requires no hinges below.

By moving the lever arm 6 from the position shown in Fig. 2, to that shown in Fig. 3, the double cranks b, c, d, and b,

c, and d, and the rods 7 and y, will pass,

into the position shown in Fig. 3, whereby the shutter is closed. By means of the double cranks, this result also is obtained; the shutter can be moved from inside the room at all times and in any direction, without the possibility of a dead center occurring, as might be the case with two simple cranks. dead play, so that all rattling of the windows is avoided.

A fixing, or locking device is provided, in which a cog shoe m, standing under spring pressure Z, is forced on to engage a cog segment, so that the double cranks can be fixed in any position.

Having now described the invention, what I claim and desire to secure is- 1. In a device of the character described, a casing, a long central crank journaled in said casing, a second longcrank parallel to said central crank, rods pivotally connecting the endsof said cranks, a shutter pivotally connected with the second long crank, and a crank arm to rotate said central crank, as herein set forth.

2. In a device of the character described, a casing, a long central crank journaled in said casing, a second long crank parallel to said central crank, rods pivotally connecting the ends of said long crank, a shutter pivotally connected to the second long crank, a cog shoe under spring pressure, a cog segment engaged by said cog shoe, and a crank arm to rotate said central crank, as specified.

3. In a window shutter fastener, having a casing, a double crank journaled in said casing, rods connecting the ends of said double cranks, means to actuate said double cranks and means to operatively connect said cranks to the shutter.

In testimony whereof I ai'lix my signature in the presence of two witnesses.

JOHANNES JACOBSEN.
